Pvc Moulds for Cover Blocks

To prevent corrosion of the rebar, it needs to be fully embedded in concrete. By code, it usually needs about 2 to 3 inches of coverage on all sides. So the cover block lifts the rebar up by about 2 to 3inches and becomes a permanent and integral part of the poured concrete, ensuring that no part of the rebar sags and minimizes that required concrete coverage during the pour.
